removes all printers currently in the Printers & Scanners preference pane.

To Reset Printing System:

Launch System Preferences

Select Printers & Scanners

In the Printers and Scanners preference pane, place your cursor in an empty area of the printer list sidebar (where the printers are listed) and right-click; select Reset Printing System from the popup.

You're asked to confirm. Press Reset.

You may need to enter administrator password or finger.

The printing system will be reset and you will need to add back your printer.

Time Machine by default will use all the available disk space on your backup drive. The good news is that you can setup a maximum limit that Time Machine can use. All you need to do is specify in megabytes the maximum space limit. You can do this by multiplying your Gigabyte preference by 1024 bytes. For example if I wanted the maximum backup space to be 100GB, I would multiply 100 by 1024 which equals 102400.
I can then enter this terminal command:

Burn ISO file to Bootable USB

20191213 This did not work for me: I'd downloaded the Win10 ISO and followed instructions to create a boot USB stick. The USB stick wouldn't boot. However I was able to use [[https://www.microsoft.com/en-gb/software-download/]] on a Windows machine to create a bootable USB stick.

You have an ISO file and you want to make a bootable USB stick from it. You will need a USB stick larger than the ISO file (e.g., ISO is 6GB, you can use a 8GB or larger USB drive. When done, the drive is completely full.)

Run terminal

diskutil list

Find name of the USB stick (e.g., /dev/disk4; we'll use /dev/diskX here)

diskutil unmount /dev/diskX

or if that doesn't work do

diskutil unmountDisk /dev/diskX

you should see a message saying unmount was successful.

Now go to finder and locate the ISO file. Right-click, and Copy <filename> as Pathname.

Back to terminal, enter part of command (don't press enter yet)

sudo dd bs=1m if=

and then paste the pathname of the ISO file to the command and then add of=/dev/rdiskX

For ISO file in smi's download directory with name silly.iso the command will look something like

Burn the ISO to Bootable CD/DVD

Drag the *.iso file from a Finder window to the Disk Utility window, drop in left pane in the empty area below the Mac drive names.

Select the .iso file name in the left pane of Disk Utility, and click Burn (top left).

The Burn Disk In: window opens and shows your CD/DVD as destination

Click Burn

When done the disk will eject

Active Window is Covered

Suppose you're running Resolve and trying to archive a project, and maybe try to rename it. You can see that the Finder window for storing the project is the active window and it's also covered by the View Projects window, it's impossible to get to it. I figured out what to do on 20200105.

Hold down Alt/Option key, move mouse to the Corner of the (Resolve main) window; see double arrow ←→ appear, double-click.

Move the main window out of the way (to another monitor for example)

For the monitor with the View Projects window is covering the Finder window, switch desktops away and then back.
